Application tiled December 19,1916. Serial No. 137,768.

To all whom t may concern: Be it known that l, JoHN Bruant, a citizen of the United States, and a resident of East Manch Chunk, in the county of Carbon and `State of Pennsylvania, have invented a nefW and Improved Heater, of vvhich the following isa full, clear, and exact description.

ie-'lhe invention relates to steam and hot Water heaters, and its object is to provide anew and improved "heater more especially designed for use in dwellings to furnish steam or hot Water to radiators for heating purposesandarranged to enable the ,user to heat the rooms more or less according to v`the seasons, that is, to give the rooms less heat during the fall and Vspring and more during the Winter, Another object is to utilize the fuel in an exceedingly Ieconomical manner and to permit :burning of solid fuel such :as coal, Wood ,and the like, or gaseous'fueh'or both at the `same time, if desired.

. In order to accomplish the desired result, use is made of two boilers, of which one is the delivery boiler for'delivering steam or hot Water to the radiators for heating the rooms, and the other is va feed Water heater connected with the said delivery boiler to supply the latter With heated Water, the said second boiler .receiving the return Water from the radiators supplied by the Vsaid delivery Vstructed furnace on Which the boilers are mounted, the furnace having a combustion chamber for directly heating the delivery boiler by the products of combustion arising from the burning fuel of the combustion chamber, the products of combustion after leaving the delivery boiler being utilized for heating the second or feed Water boiler.

A practical 'embodiment of the invention is represented in the accompanying draW- :ing respectively to Figs. 1, 2, 3, and t, show- Use is also' made of a specially coni nace 10 are mounted two boilersll and 12,

of which the `boiler 11 is preferably made in sections one in front of the other, and this boiler forms thedelivery boiler for delivering steam or hot Water to the radiatorsto be supplied. The other boiler 12 is the feed Water boilerI or heater and is connected at its front end by a lpipe 13 vith .the delivery boiler 11 to supply' the latter with heated Water. The tops of the sections of the delivery boiler 11 are provided with pipes 111 connected with a delivery pipe 15 leading to the radiators in connection Wit-h steam heating systems as in Figs. 1 to i inclusive, and the said second boi er 12 is also provided With an outlet pipe 1.6 connected with the delivery pipe 15 so that any steam that l i may be generated in this boiler 12 can pass into the delivery A return pipe L17 is lconnected with thefeed Water boiler 12 so that theV return Walter from the radiators passes intothe boiler .12 to receive a preliminary heating and to then pass by `Way of the pipe 13 into the delivery boiler 11. ln connection with hot Water systems, a hot Water outlet pipe lia leads from the rear section of the delivery boiler 1l, and a cold Water return pipe 172L connects to the top of t'he feed lWater boiler 12, all as seen in Figs. 5 to vS inclusive.

The furnace 10 is provided With a main combustion chamber 2O having a grate 21 below Which is arranged an ash pit 22, and suitable doors 28 and 241 are provided on the front of the furnace 10 and leading to the combustion chamber 20 and the ash pit 22, respectively. The combustion chamber 20 is provided at its rear with an outlet 25 leading to the rear end of the delivery boiler 11 provided with the usual smoke flues 26 for the passage of the products of 'combustion arising from the burning fuel in the fire box 2O and passing up the outlet 25. The front ends ofthe boilers 11 and 12 are connected with each other by a heading 27 to receive the products of combustion from t'he front ends of .the flues 26 and direct the said products of combustion to the front ends of the flues 28 in the other boiler 12. The products of combustion travel rearward through the flues 28and lfinally pass into a chamber `29 arranged in the rear end of the furnace pipe 15 and to the radiators.

l0 and connected with the chimney flue 30. From the foreging itwill be seen that by .thevarrangement described the products of combustion arising from the burning` fuel inthe fire box 2O first pass through the fines 26 of the boilervr ll'to highly heat the latterV and then the'products of combustion pass through the flues 28 and finally to the chim-v ,if the heater is used as a steam heater, it

is not necessary to provide an intense fire during. the spring or fall as an ordinary fire. 1s suflicient to generate steam 1n the Yboiler ll while no steam is generated in the other boiler` 12. lDuring the winter, however, a stronger fire is maintained in the fire box 20 so that steam is generated in both boilers 11 and `12.

A second combustion chamber l() is arranged in the furnace 10 directly under the delivery boiler 1l and this combustion chamber 40 is provided with two burners el for burning gaseous fuel under the sections of theV boiler 11 to heat either section or bottom simultaneously.V The rear` end of the said combustion chamber l0 is provided with an outlet 42 opening into the outlet 25 and controlled by a damper 48 having a handle 4A' extending to the outside to enable the userv `of the heater to close the opening 42 when` theburner el isvnot in use and solid fuel is burned in the fire box 20. lhen, however, the burner 4l is used then the damper f3 is opened to allow the products ofV combustion'in thevire box elOto pass through the'outlet il2 into the outlet 25 and fromthe latter through the flues 26 to the header 27 and then through'the flues 28 to the chamber 29 and the chimney flue 30. rlhe combustion chamber l0 is provided with suitable doors Ll5 for gaining access tothe boileretl and for supplying air for combustion to the burning fuel. f Y

vIt will be noticed that by the arrangementdescribed the delivery boiler l1 receives lthe heated water from the feed water boiler 12 and hence the level of the water in both boilers is always the same even when the delivery boiler only is heated sufliciently to generate steam. Considering that both boilers are approximately alike in size half the amount of water evaporated in the boiler 11 is supplied from the boiler l2 and hence the level of the water in the boiler 11 does not fall a distance corresponding to the -wholeamount ofV water evaporated but only half the distance.

.Y yThe delivery boiler ll is preferably made v in two sections .so that in, milder weather only the first section, that is, the one next to.`

the outlet 25, is heated sufficient-ly to generate steam. rlhus the user of the heater can readily regulate the'generation of steam by burning more or less fuel according to the requirement in colder or milder weather.

The heater shown and described .is very simple and durable in construction and can be cheaply manufactured, and, as above stated, either solid or gaseous fuel may be used or both, if desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. A heater, comprising two juxtaposed boilers of which one is the delivery boiler and the other is a feed water heater connected with the said delivery boiler to supply the latter withheated water, the said second boiler receiving the return water from the radiators supplied by the said delivery boiler, the said boilers having parallel smoke flues extending from front to rear, and a furnace on which the boilers are mounted, the furnace having a combustion chamber connected with the rear end of the said delivery boiler to conduct the products of combustion from the combustion chamber through the fines of the said vdelivery boiler, a connection at the front ends of the boilers to connect the products of combustion from the front end of the delivery boiler to the flues of the said second boiler and a horizontally disposed water connection between the lower portions of said boilers extending within said front connection of the boilers.

' Vextendin g from front to rear and a furnace on which the said boilers are mounted, the furnace having a combustion chamber provided with a grate, the rear end of the combustion chamber'connecting with the rear ends of the fines of the delivery boiler, a front connection connecting the front ends of the boilers with each other to conduct the products of combustion from the front ends of the 'flues of the delivery boiler to the front ends ofthe fines of the said second boiler, and a chimney Hue connected with the rear end of the said second boiler.

8. i heater, comprising two boilers of which one is the delivery boiler and the other is a feed water heater connected with the said delivery boiler to supply the latter with heated water, the said second boiler receiving the return water from the radiators boilers having smoke flues and a furnace on which the said boilers are mounted, the furnace having a combustion chamber provided with e grate, the rear end of the coinbustion chamber connecting with the rear ends of the lues of the delivery boiler, a front connection connecting the front ends of the boilers with each other to conduct the products of combustion from the front ends of the fines of the deliveryv boiler to the front ends of the flues of the said second boiler, a chimney ue connected With the rear end of the said second boiler, and a second combustion chamber directly under the said delivery boiler and provided With a, ges burner, the rear end of the said second combustion chamber being` provided with a damper controlled outlet opening into the rear end of the said lirst-nzuned combustion chamber.
